Benefits of technology

This solution allows for precise adjustment of nailing power and frequency, reducing gas consumption and noise, improving tool performance, and enhancing user comfort and safety by enabling optimal output and adjustable nailing frequencies.

Problems solved by technology

Although the NP can be adjusted by altering output pressure of the GP, the adjustment is too rough to be controlled.
Moreover, rated pressure often exists between the pump and the gun, so the wide scope of the pressure adjustment is not allowed.
However, the existing balanced valve of the air nailing gun (ANG) is fixed, so that the travel distance can not be adjusted, which is a defect resulting that the nailing power (NP) can not be adjusted.
Moreover, invariable nailing power will increase gas consumption, increase noise, and reduce live time of the nailing gun.
In addition, in the case of small nailing power needed, the scope of application of the existing ANG is limited.
For general users, the above method is difficult to master.
Moreover, since the hand feeling varies with each nailing, the nailing depths can not be uniform.
However, due to manufacturing errors, the travel distance of the balanced valves corresponds to the maximum output power of each nailing guns will be different.
Therefore, in fact, the travel distance of most balanced valves of the nailing guns does not achieve the optimum values.
Finally, the fixed travel distance of the balanced valve is not good for adjusting nailing frequency.
It is obvious that the fixed travel distance of the balanced valve is not good for adjusting nailing frequency and further impacts the using comfort.

first embodiment

[0036]The First Embodiment

[0037]Seeing FIGS. 1, 2, 3

[0038]According to the present embodiment, an adjusting mechanism for nailing power (NP) of nailing gun (NG) includes a slot which is arranged in an upper aluminum cap 1 and is co-axial with an air cylinder 2, so that a balanced valve 3 can airtight slide in the slot. The front side of the balanced valve 3 is exposed to a main chamber, and the rear side of the balanced valve 3 encloses with the inner surface of the upper aluminum cap 1 to form the control chamber 8.

[0039]The travel distance of the balanced valve 3 is restricted between the cylinder 2 and a cushion seal 4 arranged on the rear surface of the upper aluminum cap 1, wherein the cushion seal 4 is positioned on an axial position adjusting mechanism.

[0040]The position adjusting mechanism is composed of a set of screw rod and nut, wherein the nut 511 of the set of screw rod and nut is fixed on the upper aluminum cap 1, and a rotary knob 512 of the set of screw rod and nut w...

second embodiment

[0042]The Second Embodiment

[0043]Seeing FIGS. 1, 2, 4

[0044]The present embodiment differs from the first embodiment in that: an annular lining 6 is arranged in the upper aluminum cap 1, so that the lining 6 and the balanced valve 3 airtight slide fit, and the lining 6 encloses with the rear side of the balanced valve 3 and the inner surface of the upper aluminum cap 1 to form the control chamber. The other components of the second embodiment are the same as that of the first embodiment.

third embodiment

[0045]The Third Embodiment

[0046]Seeing FIGS. 1, 2, 5

[0047]The present embodiment differs from the second embodiment in that: the cushion seal 4 connects with the lining 6. The other components of the third embodiment are the same as that of the second embodiment.

Abstract

An adjusting mechanism for nailing power of nailing gun, comprising: a slot which is arranged in an upper aluminum cap and is co-axial with an air cylinder, so that the balanced valve airtight slides in the slot, the front side of the balanced valve is exposed to a main chamber, and the rear side of the balanced valve encloses with the inner surface of the upper aluminum cap to form a control chamber; the travel distance of the balanced valve is restricted between the cylinder and a cushion seal arranged on the rear surface of the upper aluminum cap, wherein the cushion seal is positioned axial position adjusting mechanism. The present invention has the advantages of capable of adjusting nailing power so as to provide maximum output power and is convenient for adjusting nailing frequencies.

Description

CROSS REFERENCE TO RELATED PATENT APPLICATION[0001]The present application is the US national stage of PCT / CN2009 / 074018 filed on Sep. 18, 2009, which claims the priority of the Chinese patent application No. 20910100556.7 filed on Jul. 7, 2009, which application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to an adjusting mechanism for nailing power (NP) of air nailing gun (ANG).BACKGROUND OF THE INVENTION[0003]Firstly, during using air nailing gun, different nailing power is usually needed in accordance with the xylon of the wood or specification of the nailing gun to drive nails into board materials, such that depths of the driven nails can meet the desired requirements of the users.[0004]The NP of ANG depends on gas pressure and gas filling volume of inner cylinder. The gas pressure is supplied by gas pump (GP) connecting with the nailing gun (NG). Although the NP can be adjusted by altering output pressure of the GP, the adjustme...
